BUS: Brain-Inspired Unsupervised Self-Reflection via Backward Prediction for Multimodal Reasoning

Jiacheng Yang, Tongying Xiao, Yunkai Dang, Cong Wang, Yuekun Yang, Qi Fan, et al.

Current Vision-Language Models (VLMs) often struggle to handle complex visual tasks that require consistent and fine-grained reasoning. Recent methods aim to train models to facilitate self-reflective reasoning, i.e., reviewing and improving the generated reasoning. However, they…

WorldRoamBench: An Open-World Benchmark for Long-Horizon Stability of Interactive World Models

Ting-Bing Xu, Jiacheng Sui, Zhe Gao, Kewei Shi, Wenjin Yang, Zhicheng Liu, et al.

Despite rapid progress in interactive world models (IWMs), existing benchmarks evaluate action following only at trajectory level and ignore memory and interaction physics. We introduce WorldRoamBench, an open-world benchmark for long-horizon stability across four dimensions, eac…
